How will I know the pH of my water?
You will need to check the pH of your water and, really, this should be done on a regular basis and a record kept of the results. We normally recommend using pH indicator strips as they are quick and easy to use. You can buy pH metres which will give more precise readings however, they must be kept very clean and cost far more than the indicator strips.
Why would I want to change the pH of my water?
If we are just talking about industrial waste water then should you wish to dispose of it then the disposal company (or water authority) regularly asks that the water be neutral. This normally means that the pH should have a reading of somewhere between 6 - 8. If you have a particular industrial process, for example degreasing, then treatment solutions will normally have a pH range within which they should operate. By testing the solution, and altering if necessary, you can ensure your pH is correct.
How will I know which product I need?
The quick answer is to use Pro pH+ if you want to raise your reading and Pro pH- if you want to lower it. The lower the reading then the stronger an alkaline your water in and the higher the pH the more acidic the water is. It is important to know this when dealing with industrial processes or waste water.
How much will I need to add?
This depends upon the total volume your are treating, its starting pH and the final value you are looking to reach so we can't really answer this question and there are too many unknowns. However, additions should be made slowly and by small amounts. For example, when regulating an 800 litre tank of water and needing to raise the pH from 3 to 7 we would first add around 1 litre of the pH+ whilst slowly mixing the solution. We allow this to settle over a few minutes then test the pH and repeat as necessary. It is important to remember that as the pH starts to change, smaller additions are required. It takes a larger addition to raise the pH from 2 to 3 than it does from 4 to 5 so make small additions, allow the water to settle between additions and take regular readings.
